Abstract [en]

BACKGROUND: The capacity to provide evidence-based practice is one of five core competencies that it is proposed all healthcare professions should possess to meet the needs of the 21st century healthcare system. New nurses are faced with a challenging work environment which, combined with shortcomings in undergraduate education and their limited clinical experience, may affect their evidence-based practice.

OBJECTIVE: The aim of this study was to prospectively examine the extent of Swedish nurses' evidence-based practice during the first five years of professional life.

DESIGN: An observational longitudinal study, with yearly data collections over the course of five years. SETTINGS: Data was collected in two national cohorts (named EX2004 and EX2006) of Swedish registered nurses. Nurses in EX2006 were followed yearly during the first three years after graduation and nurses in EX2004 yearly three to five years after graduation. They had completed a three year academic nursing program and mainly worked in in-patient care settings.

PARTICIPANTS: Participants were recruited while studying at any of the 26 universities in Sweden. A total of 2107 (EX2006) and 2331 (EX2004) nursing students were eligible. 1207 and 1227 nurses were included in the current longitudinal samples. The nurses had a mean age of 31.2/33.9years old and a majority were female. The cohorts were representative of the general nursing population.

METHODS: Data was self-reported and collected through annual postal surveys. Evidence-based practice was conceptualized as a process and measured with an instrument including six items. Data was analyzed using latent growth curve modeling.

RESULTS: The extent of evidence-based practice was stable, between the two cohorts and over time. Individual differences existed and remained stable over time. However, the extent of practicing the different components of evidence-based practice on a monthly basis varied considerably, from 10% of the nurses (appraising research reports) to 80% (using information sources other than databases to search for knowledge).

CONCLUSION: The extent of evidence-based practice remained unchanged during the first five years of professional life. It appears important to enhance both the contribution of undergraduate education and the contextual conditions in work life, in order to improve evidence-based practice among newly graduated nurses.
